Hydrogen Fuelled I.C. Engine

Vikas Sharma

Abstract: : In this paper, initially in this paper some design modication is required for using hydrogen as a fuel in existing four stroke gasoline engine that has been discussed. Combustive properties of hydrogen fuel have been discussed. After that the performance and emission characteristics of a conventional four cylinder spark ignition (SI) engine operated on hydrogen and gasoline has been reviewed. The variations of torque, power, brake thermal eciency, brake mean eective pressure, exhaust gas temperature, and emissions of NOx, CO, CO2, HC, and O2 versus engine speed are compared for a carbureted SI engine operating on gasoline and hydrogen.
